For the fourth consecutive year, a national business publication has named SeQuel Response to its list of the fastest-growing private companies in the U.S., putting the multichannel growth agency in the top 10 percent of applicants nationwide.

“Of the tens of thousands of companies that have applied to the Inc. 5000 over the years, only a fraction have made the list more than once,” said Inc. Media President and Editor-in-Chief Eric Schurenberg in a letter to SeQuel’s leadership. “A mere one in ten have made the list four times.”

SeQuel, which launched in Eden Prairie, Minn. in January 2010, finished last year with $36.7 million in net sales, marking three-year revenue growth of 234 percent.

“Our No. 1 goal is to help our clients grow as rapidly as possible,” said SeQuel’s Co-Founder and Chief Operating Officer Jay Carroll. “As excited as we are to be recognized by Inc. Magazine yet again, we’re even more excited about what it means for our clients: Our direct mail and digital marketing campaigns are helping them grow at rates that are justifying ever-increasing investments in these channels.”

The award comes on the heels of a pivotal year for the future of the young agency. In January 2016, SeQuel supplemented its direct mail capabilities by launching a digital marketing division that specializes in paid social, search-optimized content marketing, paid and organic search, programmatic display, email, mobile channels and landing-page optimization.

Since taking over all digital marketing efforts for Northwestern Health Sciences University, SeQuel has already helped the nonprofit grow its enrollment-inquiry volume by 673% year over year.

“The most effective delivery system will always vary based on the product, offer and audience,” Carroll said. “We’ll continue using direct mail to help our clients acquire hundreds of thousands of new customers per year—for one of our clients, mail brings them more than $30 million in new revenue every month. Now we’re simply applying those time-tested direct-response principles across digital media to help accelerate our clients’ growth even further.”

This year marked another fourth consecutive honor for SeQuel, as it made its latest appearance on the Minneapolis-St. Paul Business Journal’s list of Top Ad Agencies in the Twin Cities. SeQuel came in at No. 7 on the 2017 rankings by revenue, moving up two spots from a year ago.
